ENERGY SAVING TIPS
To save energy, time and money, Bosch recommends
the following:
Always spin dry the laundry in the washer at the
highest recommended speed for the fabric type.
The highest spin speed will result in a dryer load and
shorten the drying time and amount of energy
required to dry the load.
Spin dry delicate washing before tumble drying.
Load the dryer properly. Do not exceed the maximum
load (see CYCLE SELECTION CHART).
Always clean the lint filter after each use of the dryer.
OPERATING TIPS
Follow the fabric care labels on the clothing.
Avoid very small loads. When only one or two items
need drying, add a few similar items to improve
drying efficiency.
Do not mix heavyweight and lightweight clothing.
Do not dry wool or fabrics with a wool content
Do not dry fabrics that do not allow the free passage
of air (for example, GORETEX)
Do not dry delicate fabrics such as, silk, synthetic net
curtains, etc.
BEFORE USING FOR THE FIRST TIME
Before beginning to use your dryer for the first
time:
1. Check to make sure that the voltage on
which the dryer is to operate is the same as
shown on the rating plate.

softener stains.
5. Close the Door
Check the area around the drum opening to make
sure that nothing is caught on the edge or hanging
outside the drum and close the door making sure the
door clicks into place and is fully closed.
Note: If the door is not fully closed
the dryer will not operate.
6. Select the Drying Cycle Desired
The Bosch dryers can be operated in either the
Electronic Auto Dry Cycle mode, which uses the
Duotronic moisture sensing system, or in Time Cycle

machine will start. If one of the Auto Cycles has been
selected the Duotronic system will continuously
monitor the moisture level of the load and display the
progress in the ‘‘Moisture Level Indicator Lights.’’ If
a timed cycle has been selected, either Heated Dry
or Air Fluff, the minutes remaining in the program will
be shown in the ‘‘Cycle Countdown Display.’’
The program will continue to the end, when the
‘‘End’’ indicator lamp will become illuminated.
And if the ‘‘End of Cycle Signal’’ has been selected
a signal will sound.
Note: If using the Auto program at the beginning
of the cycle there will be numerous rotations
in each direction with complete stops in
between for approximately 90 seconds.
There is nothing wrong with the machine,
it is taking a reading on the moisture of the
load to determine how long to dry.
Note: If the load is not removed, the drum will,
for the following 35 minutes, rotate at brief
intervals to prevent wrinkling (Anti-Crease).
After 35 minutes this feature will cease its
function. It is recommended that the dryer
be unloaded no later than 35 minutes after
completion of program to avoid wrinkling.

Dryer Electrical Cord
The Bosch dryer comes with a 4-wire power supply cord
pre-installed. This cord fits a 4-wire receptacle as shown
in the upper section of Figure 11.
If your receptacle is a 3-wire receptacle, as shown in the
lower section of Figure 11, a 3-wire ‘‘Dryer Cord’’ must
be purchased locally. The 4-wire cord must then be
removed and the 3-wire cord installed in its place, as
instructed in following section.
When purchasing a 3-wire power supply cord make sure
the cord meets following requirements:
U.L listed in the USA, CSA listed in Canada
240 volt rated (minimum)
30 ampere
Type SRD or SRDT
Five feet long (minimum)
4-wire receptacle
(14-30R)
Dryer shipped with cord to fit
this type 4-wire receptacle.
3-wire receptacle
(10-30R)
If you have 3-wire receptacle,
like this, a 3-wire dryer cord
must be purchased locally.
Figure 11.
This appliance must be grounded. In the event of
malfunction or breakdown, grounding will reduce the risk
of electric shock by providing a path of least resistance
for the electric current. This appliance is equipped with
a cord having an equipment grounding conductor and
a grounding plug. The plug must be plugged into an
appropriate outlet that is properly installed and grounded
in accordance with all local codes and ordinances.
Improper connection of the equipment grounding
conductor can result in a risk of electric shock. Check
with a qualified electrician or serviceman if you are in
doubt as to whether the dryer is properly grounded.
Some local codes may require a separate ground. In
such cases, the required accessory ground wire, clamp
and screw must be purchased separately.
Never ground the dryer to plastic plumbing lines,
gas lines or water pipes.
The receptacle for the dryer cord must be located so that
the power supply cord will be accessible when the dryer
is in the installed position.
The WTA 3510, electric vented dryer, is intended to be
vented to the outdoors. To prevent build-up of moisture
and accumulation of lint indoors, as well as to maintain
maximum drying efficiency, it is recommended that the
Bosch WTA 3510 be vented to the outdoors.
Four-inch (approx. 100 mm) diameter ducting should be
used. Use either rigid metal or flexible metal ducting
material. DO NOT use non-metal duct with this dryer.
Exhaust ducts should be as straight as possible.
Exhaust ducting longer than recommended can extend
drying time, can collect lint and may effect dryer
performance. Joints should be secured with duct tape.
DO NOT use screws to secure joints as lint can collect
on the screws. See Step 4, Exhaust Duct, in following
section titled INSTALLATION for recommended routing
and duct length calculations.
The exhaust duct must end with an approved exhaust
vent hood with swing out damper(s). DO NOT use an
exhaust vent hood with magnetic latches. To avoid
restriction of exhaust the outlet must be a minimum of
12 inches (30 cm) above ground level, or any other
obstructing surface. See Figure 17.
The WTL 5410, electric condensation dryer, dries by
condensing the moisture from the dryer air and then
pumping this condensate out of the dryer.
The WTL 5410 must have its condensate hose
connected to a suitable drain. See Step 5, Condensate
Hose Connection, in the following section titled
INSTALLATION.
A stacking kit is supplied with each dryer in order to
stack Bosch dryer upon a Bosch washing machine.
This part is only necessary if stacking the units is
desired.
As an additional accessory for purchase, Bosch offers
a stacking kit for a Bosch washer and dryer that
incorporates a pull-out-tray. The tray offers an area for
folding and easier unloading of the dryer. See your local
dealer for availability and price.

The Bosch dryer can be built-in: that is, you can install
the Bosch dryer under-counter in a kitchen cabinet
opening. The cabinet opening should be square and
have the dimensions as shown in Figure 13.
Note: If installed under a countertop, the countertop
must be continuous and securely attached to
neighboring cabinets.
DO NOT install the dryer in an area where gasoline
or other flammable materials are kept or stored.
The dryer must be installed in a room that is adequately
ventilated. Make sure there is an adequate supply of
fresh air. Both the WTA 3510, electric vented dryer, and
the WTL 5410, electric condensation dryer need an
adequate supply of fresh air for optimum performance.
DO NOT install the dryer in a closet with a solid door.
The dryer must have make up air as specified on
page 17 under Ventilation Requirements.
INSTALLATION
Step 1
Unpack the Dryer
Carefully remove the packing material from the outside
of the dryer.
Step 2
Inspect the Dryer
Thoroughly inspect the dryer, prior to installation, for
possible freight or cosmetic damage.
Step 3
Position Dryer near Installation Area
Move the dryer so that it is within four feet of the desired
position.
Note: Corrugated packing material may be used to
protect the floor. Do not use corrugated material
with staples.
Step 4
Exhaust Duct
(Model WTA 3510 only!)
The WTA 3510 must be exhausted to the outdoors.
1. To reduce the risk of fire, this dryer MUST BE
EXHAUSTED OUTDOORS.
2. DO NOT use non-metal duct with this dryer.
3. DO NOT use duct smaller than 4 inches in diameter.
4. DO NOT use exhaust hoods with magnetic latches.
5. DO NOT exhaust the dryer into a chimney, furnace
cold air duct, attic, crawl space, or any other
ductwork used for venting.
6. DO NOT install flexible duct in an enclosed wall,
ceiling or floor.
7. DO NOT crush or kink the duct.
8. Do clean and inspect the exhaust system on
a regular basis; once a year, at a minimum.
9. The exhaust duct must end with swing out
damper(s).
Be sure to install the exhaust according to all governing
codes and ordinances. Rigid metal duct is recommended
for venting this dryer. If flexible metal duct is used, be
sure it is fully supported when the dryer is in its final
position. Excess ducting should be trimmed off to avoid
sagging or kinking of the ductwork.
The duct may be connected to the left, right or back of
the WTA 3510, electric vented dryer. If connecting to the
left or right hand side of the dryer, remove the sealing
cover from the side to be used, as shown in Figure 14.
Figure 14.
The sealing cover should then be placed over the open
vent opening at the back of the dryer, as shown in
Figure 15.
Figure 15.
The connecting piece supplied with your WTA 3510
dryer must then be inserted in the vent opening that will
be used. See Figure 16.
Figure 16.
The ducting system of the dryer, for optimum
performance, should be as short as possible with
a minimum number of elbows. Your WTA 3510 electric
vented dryer will work best when the venting system has
as few restrictions to the flow of air as possible.
Whether installing to an existing venting system or a new
venting system, make sure that all ducting is clean and
free of lint and does not exceed the length per elbows as
shown in Table 1, below:
Maximum length of duct

Table 1.
Every elbow must have a minimum diameter of 4 inches
(10 cm).
The above table assumes the use of an approved
exhaust vent hood with a swing out damper. DO NOT
use an exhaust vent hood with magnetic latches.
To avoid restriction of exhaust the outlet must be
a minimum of 12 inches (30 cm) above ground level, or
any other obstructing surface, as shown below, in
Figure 17.
12” (30 cm) min.
Figure 17.
Step 5
Condensate Hose Connection
(Model WTL 5410 only!)
The WTL 5410 must have its condensate drain line
installed and run to a suitable drain. The connection
for the condensate hose is located on the back of the
WTL 5410, see Figure 18.
Figure 18.
Connect the condensate drain hose to the dryer.
The other end should then be placed and secured at
a nearby sink or drain, or if installed with a washer it
may, room permitting, be installed next to the washer
drain hose and drained to the same drain used by the
washer.
Be sure to follow all local codes and regulations in
running the condensate to a suitable drain.
